To all whom it may concern:

Beit known that I, EUGENE A. PORTER, a citizen of the United States, residing at Bowling Green, in the county of 'Varren and State of Kentucky, have invented certain new and useful Improvements in Corn Splitting and Crushing Machines, of which the following is i a full, clear, and exact description, reference l being had to the accompanying drawings, forming part of this specification, in whichi Figure l is a perspective view of my improved machine. Fig. 2 is a longitudinal section through the line a' x.

The object of my present invention is to provide a machine for splitting and crushing corn in the husk and ear for feeding stock, the improved machine being of such construction that the corn, in coniradistinction to being ground into a pulpy mass, is simply crushed and split into small pieces to avoid waste, which occurs when it is fed in the ear, and also to enable it to be easier eaten by stock; and my invention consists in the construction and combination of devices hereinafter explained and claimed, and is an improvement on the invention covered by my Patent No. 285,512 issued to me September 25, 1883.

To enable others skilled in the art to make and use my invention, I will proceed to de scribe the exact manner in which I have carried it out.

In the drawings, A represents the framework, on which are placed the rollers B B, operated by any ordinary system of gearing.

In my former patent the sharp ribs for cutting the shucks on the ears of corn as they passed between the rolls stood at a radius from the center of the roll. With this construction I discovered that there was great danger of the ear being crushed before the cutting-blades were fairly brought into action on the shuck, and after the ear had been crushed the cutting edges failed to sever the shuck. To overcome this difficulty is the special object of my present improvement.

The roll B is formed with the concave grooves b,and on the dividing-lines between the grooves I secure cutting-blades b', inclined in the di- CRUSHING lVlACl-ilNE.

Patent No.360,045, dated March 29,1887.

Serial No. 208,608. (No model.)

B is formed with corrugations or projections arranged opposite the grooves b on the roll B.

Along the longitudinal centers of these projections I secure corresponding cutting-blades, d, inclined in the direction in which the roll travels. The result is that the cutting-blades b and d incline in the direction in which the rolls rotate, and by this construction they are caused to act on and cut the shuek before the ear becomes crushed.

In order to secure the feeding of the ears endwise between the rolls, I have constructed the hopper O with a pivoted bottom provided with a bar, O', extending through a vertical slot in the front of the hopper, and which is lifted by the cam D on the shaft D', or by any other well-known means, so as to give the bottom of the hopper a shaking motion, while the bar C tends to cause the ears of corn to feed end foremost between the rolls, so as to enable the cutting-blades to sever the shucks.

In order to more completely mutilate or cut the shuek, the cutting-blades may be made slightly scalloped, so as to partially envelop the ear as it passes between them.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The roll B, formed with concave grooves b, and provided with the cutting-blades b, in combination with the roll B', formed with the corrugations or projections and provided with the cutting-blades d, said blades b and d being inclined in the direction in which the rolls rotate, substantially as and for the purpose described.

2. An improved corn splitting and crush ing machine, comprising the rolls B B, having the cutting-blades b and d, as described, the' hopper C, having a pivoted bottom, the bar G, projecting through a slot in the front of said hopper, the shaft D, and the cam D, all constructed and arranged to operate as herein set forth.
